Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fiber types?Natural (hemp, cotton, manila) and Synthetic (nylon, polyester, Dyneema, Kevlar)
2. What is the construction techniques?Laid (twisted strands) and Braided (interlaced strands), each offering distinct properties
3. How do ropes become so strong?Fibers are spun into yarns, then twisted into strands, and finally twisted again in the opposite direction. This layered twist creates friction and a helical shape that holds the rope together.
4. Why do some ropes have braided patterns?Braided ropes weave strands together in a special pattern. This makes them flexible, resistant to wear, and keeps a steady thickness, which is useful for climbing and sailing.

Ultra-high-molecular-weight polyethylene (UHMWPE): A synthetic fiber known for extreme strength, abrasion resistance, and low weight.
Aramid Fiber: A class of synthetic fibers known for high tensile strength and heat resistance, like Kevlar.
Sheath/Core Construction: A type of braided rope with an outer sheath protecting an inner core of strands.
