| Summary, etc. |
This capstone study investigates the effects of nipa palm frond fibers (NPFF) as<br/>reinforcement in coconut leaf sheath (CLS)–low-density polyethylene (LDPE) composite<br/>boards, addressing three critical gaps: CLS-LDPE boards not passing modulus of rupture<br/>(MoR) standard, the absence of thermal conductivity data for natural fiber-thermoplastic<br/>composites, and the environmental impacts of agro-waste disposal. Five mix designs were<br/>developed with a fixed 70:30 LDPE:CLS ratio and varying NPFF content (0%, 1%, 3%, 5%, and 7%) after alkali treatment (5% NaOH) to a uniform 15 mm length. Boards were<br/>produced via twin-screw extrusion, two-roll milling, and compression molding. Physical<br/>(density, water absorption, thickness swelling), mechanical (MoR, internal bond, impact<br/>strength), and thermal properties (thermal conductivity) were evaluated following ASTM<br/>D1037, D790, D5420, and C518, and compared with PNS ISO 16893:2017 (P-GP MR2)<br/>standards. Results show that all mixes passed the required limits for water absorption<br/>(<14%), thickness swelling (<12%), and density variation (<±10%). MoR increased from<br/>12.94 MPa (M1, 0% NPFF) to 21.60 MPa (M4, 5% NPFF), exceeding the 13 MPa<br/>requirement. Thermal conductivity (0.0954–0.1114 W/m·K) was comparable to<br/>commercial PVC. Optimal reinforcement was at 5% NPFF (M4), with 1% NPFF (M2) as<br/>an economical alternative. The study concludes that NPFF-reinforced CLS-LDPE boards<br/>meet the P-GP MR2 standard for tropical humid conditions, offering viable ceiling/wall<br/>applications. This work benefits local nipa farmers in Pamplona, Cagayan, and aligns with<br/>the TUP research agenda on “Advanced Industrial and Energy Technologies” and on<br/>UN-SDGs 9, 11, and 12: on sustainable industrialization, resilient communities, and<br/>responsible consumption.
