WLFT

Introduction

WLFT is

WLFT is"Woven Long-Fiber Hybrid Thermoplastic Composites"
SambarkLFT provides WLFT for various parts in automotives, construction and industry applications as new materials to replace metals.

WLFT is a new material of sheet that is hybridized with fully impregnated WFT(Woven Fiber Reinforced Thermoplastics) and LFT(Long-Fiber Reinforced Thermoplastics) sheets.

Characteristics
